Definitions

  • the invention relates to a hydrostatic-mechanical power split transmission, in particular with a common housing for at least two hydrostatic machines and a planetary gear.
  • connection paths are often unfavorable here and require complex and fragile piping.
  • a particular disadvantage is the high noise level emitted to the outside, in particular of the hydrostatic machines.
  • a generic arrangement according to DE-A-31 25 123 is known.
  • the subject of the application and the subject of DE-A-31 25 123 are based on the same task, but the solutions for the identical task are very different, partly resulting from the different assignment of the individual components of the transmission.
  • the hydrostats are connected in alignment with the drive shaft and the planetary gear is arranged axially parallel thereto, furthermore two housings are provided, whereby the space requirement of the unit is considerably increased.
  • the invention has for its object to provide an easy-to-assemble, mechanical-hydraulic transmission unit with minimal noise level and the smallest space requirement.
  • the power split transmission has a planetary gear aligned with the motor and transmission output shaft, at least two hydrostatic machines arranged axially parallel to the planetary gear, a control or connecting block and an intermediate shaft with transmission stage and clutch and couplings, and the connecting lines of the axes of the hydrostatic machines and the planetary gear form a triangle and the hydrostatic machines are arranged tangentially with their peripheral surfaces, the envelope of the planetary gear, that the planetary gear has four shafts in a known manner, in at least one operating range drive and output and each hydrostatic machine each on a different one
  • the shaft of the planetary gear can be effectively set and preferably at least one of the hydrostatic machines can be switched to another operating range by means of a clutch and that the hydrostatic machine and the connection or control block are connected to one another as a pre-assembled unit, preferably in a U-shape.
  • a unit designed in this way requires only a minimal amount of space and can also be preassembled inexpensively.
  • An essential inventive idea is the arrangement of the unit comprising hydrostatic machines and control block, which is preassembled from the various elements and which is arranged together with the other components of the transmission in a housing surrounding the elements at a short distance.
  • the combined mass of two hydrostatic machines and control block with vibration-related smaller amplitudes and favorable mass behavior results in a significant reduction in the noise level of the noise emanating primarily from the hydrostatic machines .
  • the power split via the planetary gear with an additional intermediate shaft leads to a reduction in performance in the hydrostatic machines, which causes a further reduction in the noise level.
  • the circuit which takes place on the intermediate shaft, extends the entire conversion range and thus reduces the necessary hydrostatic power.
  • control heads are arranged at such an angle in hydrostatic machines with inclined axes that their ends almost touch and extend tangentially to the enveloping circle upwards or downwards.
  • the smallest installation space for the elements is also achieved with these bodies, which run in a complicated manner in space, so that the height and width of the housing can be made as small as possible.
  • the preassembled unit is mounted in the housing via vibrating metal elements. This results in a further structure-borne sound absorption, which has a favorable effect on the overall noise level.
  • the invention is designed in such a way that the housing for the insertion of the assembly unit has an opening which can be closed by a cover.
  • This design enables the gear unit with its hydrostatic components to be installed in the housing in a particularly quick and economical manner.
  • the hydrostatic machines are with the planetary gear via axis misalignment, angular misalignment and torsion compensating couplings, e.g. B. connected via vibrating metals.
  • the elastic couplings are enclosed by facing shells, arranged in front of the housing and can be fitted from the end faces via thru axles.
  • the units inserted from below or above can be connected to one another in this way without hindrance.
  • the front shells also prevent sound from escaping from the front wall of the housing.
  • a vibration-insulated plug-in pipe connection preferably of articulated design, is arranged between the housing and the control or connecting piece for inserting the preassembled unit.
  • the pressure oil introduced by the feed pump via the oil filter is fed through the housing into the control or connection block.
  • the connection parts are designed so that pipe vibrations are not transmitted to the outside.
  • the connections to the cooler or pressure accumulator can be designed.
  • Fig. 1 shows two hydrostatic machines (1) which are firmly connected to a control or connection block (11) to a pre-assembled unit (yoke) (12).
  • the hydrostatic machines are above z.
  • the gear elements are arranged in a housing (6), the preassembled unit (12) being mounted in the housing (6) in a noise-insulated manner via 4 oscillating metal elements (13).
  • the planetary gear (2) preferably consists of a 4-shaft double planetary gear set.
  • the sun (14) is connected to the drive shaft of the motor, the planet web (15) to the output shaft (20).
  • the housing (6) has an opening for the insertion of the hydraulic gear unit, so that it can be easily inserted and installed.
  • the elastic couplings (5) are connected to the curved tooth couplings (4) and the output shafts (7) via thru axles (18). In order to prevent sound emerging in the end face area, facing shells (17) are provided above the elastic couplings (5).
  • Fig. 2 shows the transmission in the front view (intermediate shaft not shown), in particular the assignment of planetary gear and hydrostatic machines is clearly recognizable, namely that the connecting lines of the axes form a triangle.
  • the hydrostatic machines are provided with inclined axes (9), as is often the case commercially, these are oriented approximately tangentially to the enveloping circle (10) of the planetary gear, preferably at 45 °. In this way, the smallest possible space requirement for the entire elements with the smallest height and width dimensions is achieved. This applies above all to the difficult structural design of the hydrostatic machines.
